AMD Radeon Performance Enhanced SSDT

[scab99]

Please i need some help...
I'm using OC and i've followed the guide on page 1, however it would seem that i having a few issues.
It would seem that i'm not getting any acceleration with my RX580 and my HDMI ports are not working. I thought i had it figured out, however i was mistaken.

I'm running Catalina

EFI folder attached
Any assistance would be greatly appreciated.

EDIT: I'm now getting acceleration using iMacPro1,1 however still no dice with the HDMI.

EDIT 2: so It HDMI now seems to be working after i removed agdpmod=pikera

@mattystonnie , if you wouldn't mind going through my EFI folder and advise if there are any optimisations which i could do. Asking you as you seem to be the authority in this area

Hello everyone, I'm desperate and I need help ...
Clover, Catalina 10.15.7 with Asus Arez Vega56 works good...but if you turn off / turn on the monitor, the cursor and windows start to stutter. if you pull out and insert HDMI, it also starts to stutter ... only reboot solves the problem

I also have an Nvidea GT710 and the system works perfectly! ...

I've been trying for a month to find the reason and all without results ...
ps: There was no such problem on MOJAVE system with Vega56 ...

I will be VERY grateful for any help ...

P.P.S - i tried RX5600xt on my system but with CLOVER i got reboot. With OPENCORE and agdpmod = pikera I was able to start RX5600xt, but I also have cursor micro lags...

Do you guys know what do I need to do to make hdmi audio work? I already have the latest version of WhateverGreen in the efi folder, in the hackintool application it appears like this in the screenshot I sent, in the sound settings the hdmi audio output appears, but I can't increase or decrease the volume and it doesn't come out sound on the loud speaker of the tv that is connected to the pc, has any boot-arg that needs adc in the config.plist or has to inject something somewhere else? I tried to use a kext that I found researching about it called hdmiaudio.kext but without success, and I don't have speakers to use on the motherboard's sound output

My videocard is an RX 5500xt 4GB from Gigabyte

Thanks for the very interesting work... I just tried out the SSDT for RX580, and got the following results (before and after sleep)...

Before SSDT:

OpenCL:

Metal:

After SSDT:

OpenCL:

Metal:

So overall, a very mediocre increase in performance... but GPU die temp has come down anywhere from 5c to 10c, which is a real achievement!

Hope someone finds this info useful. PS. Using iMacPro1,1 SMBIOS without agdpmod=pikera, Sapphire Pulse RX 580 8GB

Anyone else's RX5700 XT does a load buzzing noise when moving the mouse/scrolling on pages? Like a very load coil whine?
I saw a lot of reports of this using Windows, but after drivers updates from like 6 months ago there are not a lot of reports.
This happens to me but only on my MacOS boot (I guess because of outdated drivers?). When I restart and boot into Windows it doesn't happen on windows. Only on MacOS.

Any fix for this?

I have this with Sapphire Nitro+ RX5500XT. It's annoying as hell in a quiet room and I hear it in both Windows 10 and macOS Catalina.

Nice! My geekbench 5 score increased!
by using op's 5700xt SSDT and this https://github.com/Pavo-IM/AGPMInjector

OpenCL: 74115 (before 73396)
Metal: 69360 (before 68322)

Thank you for your wonderful guide.
It worked with "HP8300CMT RX570 Opencore 0.6.3 Catalina 10.15.7" with "PEGP to PGP0" setting.

this not worked for me. Is it possible that my ssdt path is not correct?
thanks in advance

I may have done something wrong, but I cannot get the Orinoco framebuffer for my RX580. Using OC 0.6.3 on Big Sur, I install the RX580 SSDT and AGPM.kext, adding them to the config.plist but it still shows RadeonFrameBuffer.

Any help would be appreciated.

edit: FWIW, I have a MSI 8GB RX580 card with 2 x HDMI, 2 x DP, 1 x DVI

edit #2: I removed the SSDT and instead used the DeviceProperties detail from https://www.tonymacx86.com/threads/amd-radeon-performance-enhanced-ssdt.296555/post-2118592

This enabled the orinoco framebuffer. Success! Except, it doesn't solve the problem I hoped it would address.

System and Samsung 4K HDR TV boot fine. But if I turn off the TV and turn it on again, there is no signal. Have to reboot the hackintosh every time.

Anyone know what that is caused by?

I have updated my attached files.

Some before and after geekbench scores. Running an ASRock RX 5500 XT. Not too bad, especially on the OpenCL score!
